It will help but not enough that you will be able to tell.
With gas mileage it's a lot of little things you do that will all add up.
Proper tune, K&N filter, lightening the car and Synthetic oil will help.
Sythentic oil is probably the only thing that will make a noticeable difference on it's own unless it's poorly tuned.
The best thing you can do to improve mileage is to tape an egg to your brake and gas pedals. Seriously, the way you accelerate and decelerate will make more difference than anything else you do.
Thanks a lot guys.
I've already started changing my driving style some and it seems to be helping. I now have a combined mpg of around 23, better than the epa rating of 19.
Here is mine check out the MPG trend. But 28 mpg in the city is a bit high, Have not checked mine in the city but i can tell by the fuel gauge its not that high
Just got back with the bird on a road trip. Checked mileage 153 miles on 5 gallons = 30.6 !! This was flat ground cruise . 273 miles on 10 gallons =27.3 this was hills coming up I-81 in VA. How in the world ??? I still cant belive that. It was a steady cruise trip 75 MPH 2300 or so RPMs
I get a combined of about 28. I drive a 90 mile commute round trip every day. I get a full week (5 round trips) before needing to fill up. I put roughly 16 Gallons in every fill-up.
90x5 = 450 miles
450miles/16gal = 28.12 MPG
Currently I have a stock tune (set up for the 3.27's). I'm going to get a tune on the car to REALLY make use of the 2.73's that are in the rear dif, and then see if I can get into the 30's.
I'm hoping for better with a more conservative tune if possible. I'm hoping to get into the 30's. I've already backed off my acceleration curve. I accelerate about as slowly as a delivery truck on my daily commute, and use cruise to keep me at about 60 MPH where I can use it.
I never said 28 mpg city. I wish. I drive a total of 90 miles round trip to school and mostly drive freeway but hit traffic going to school and coming home. I got an average of 28 mpg and got a little over 350 miles with a quarter tank left. I probably could of got 30 mpg driving 65 the whole way with no traffic.
i've taken it down to just under a gallon on one scary occasion:leftright , so i'd say 17-1/4 usable lol
as for the silencer debate its just something to put in a modification list before any real work is done. also, there is waaaaaaaaaay too much discussion on this subject
I agree, I noticed no difference when I took mine out. I used to get avg of about 28 mpg mixed driving( NYC) but I went to change the plugs and I put in bosch plats 2s or what ever they are called and im down A LOT. so im thinking of going back to coppers but I wonder if anything else has caused this drop. and yes I am light on the pedal, dont go above 2k on acceleration.
Ummm. The silencer removal is a free mod. It may not gain you much but it doesn't hurt either. If you have a spare 20 minutes while you are under the hood, take that thing outa there.
I haven't necromanced it yet........still a nice candle lit dinner at home to come
